is the savage s40 as reliable to a honda of the same class? thanks to all of you
The class (large displacement air-cooled single cylinder) no longer exists in the US.
The only purely air-cooled single cylinder (the CB1100 is air/oil cooled and is multi-cylinder) street bike that remains in Honda's inventory (in the USA) is the Grom/Monkey/Cub horizontal-single. The basic design of that engine has been in production since the 1960's. Millions have been produced by Honda directly, and additional millions have been built under license. That engine has grown is size from 49cc (making about 4hp) to 125cc (making about 12hp). There are licensed engines up to 180cc of that basic design making nearly 20 hp. The latest version have EFI.
Suzuki's history of making air-cooled four-stroke singles is almost as impressive. The engine in your S40 represents one of Suzuki's most "modern" air-cooled engines because Suzuki hasn't really invested in air-cooled engines since the 80's.
Whether made by Honda, Suzuki, Yamaha or Kawasaki - these low tech air-cooled engines are designed to work in the harshest conditions with minimal maintenance. A well maintained air-cooled single pulling duty in north America will last longer than the frame it has been installed.
